So I just built a brand new computer. I completely updated my motherboard's BIOS (Asus z87-a) to help better with PCI Express 3.0 compatibility. I have an 850 watt PSU, the card is seated properly, and plugged into the PSU properly. When I try installing the newest Nvidia graphics driver (327.23 WHQL), it will crash every single time, saying the "kernel has stopped responding and has successfully recovered". Also I'll get funky colors, stops loading Windows 8 tiles, and extreme lag. Sometimes the computer doesn't even log in before it crashes.
Currently I have the card disabled in device manager. I've tried both PCI Express 3.0 slots, tried using the drivers on the Zotac disk, and the brand new driver previously stated (327.23 WHQL) from Nvidia, neither worked. I've completely wiped the Nvidia drivers using Drive Sweeper, but still it did not work. Also, in device manager, my card comes up as "Nvidia GeForce GTX 680", when it should come up as a GTX 760.
I talked with Zotac, the card has a GTX 760 model number, so it shouldn't come up as a GTX 680. My guess is that this is a bad card. Any other thoughts would be appreciated.
